This invention relates to boxes and has special reference to boxes made of cardboard or other appropriate material of suflicient stiliness to retain a desired shape and having an outside base member with cut or raw edge and held in connection with the bottom 1nde-.

pendently of the side wall.

An object of the invention is to provide a box having its side walls held in connection with the bottom in combination with a cardboard base having a cut edge and held in connection with the bottom by means other than the means holding the sidewall in connection with the bottom.

Another object of the invention is to provide an improved box of approximate heart shape and having the side walls connected.

withthe bottom and top respectively of the box; in combination with a base and a top covering portion secured to the bottom and to the top respectively and by fastening means applied after the connection of the side walls to said bottom and top and having their marginal edges extending beyond the side walls ofthe bottom andthe top-so as to shield and guard the connections of the side walls with the bottom and topof the box, said base and said top covering portion being attached to the bottom and top of the box respectively by means other than the means connecting the side walls of the bottom and top ofthe box respectively.

Another object of my invention is to provide a box of novel and improved construction which may be manufactured largely by machinery so as to eliminate objectional con-- 1 ditions of hitherto costly hand manufacture.

This specific object may be obtained by providing a connection uniting the side walls with the bottom and top of-the box respectively, which connection is different or'separate 'fiom the means uniting the'base and top covering portion with the bottom and top of the box respectively. 1 a 7 Another object of the invention is to provide a box of the type and of the character mentioned wherein the ends of the side walls are secured together by means other than the means uniting the side walls with the bottom and with the top'of the box respectively.

Other objects will appear from the following description, reference being made to the drawings in which Fig. 1 shows a blank from which the box may be made, the scoring and bending .lines .1925. Application mbeing indicated by lines composedof dots and dashes.

Fig. 2 is a top plan view of the box with prises a rear portion 2, the ends of side edges of which converge rearwardly and-which extends the full width of the box. Additionally the body portion 1 comprises a middle portion 3, the side edges of which convergeforwardly from intersection with the side edges of the rear portion 2 and which "intersect the forwardlyconverging side edges of the tront portion 4 which is in the sha e of a triangle.

The sideed es of each portion of the body 1 are forme integral with rectangular wallforming tabs 5, the width of which is equal to the length of the "respective side edges with which said tabs are integrallymnited.

Each of the tabs 5 is of uniform width throughout its length so that when said tabs are turned perpendicularly to the body comprisin the portions 2, 3 and 4 the side edges of sai tabs are 1n abutting contact, as clearly shown in Fig. 2 of the drawing. These tabs 5, as stated in the brief description of Fig. 1 of the drawing, are defined from the portions 2, 3 and 4., with which they are respectively united, by score lines 5. The score lines 5 definin the respective tabs 5 intersect the score lines 5" for the adjacent tabs at the points of union of the tabs with the body portion 1 and it is along these score lines that the tabs 5 are jolded soas to bring their side. edges into abutting contact or into close relationship.

According to this form of the invention the side wall of the box is formed integral with the bottom of the box. It is apparent that the means uniting the side wall with the bottom of the box is difierent from the means by which the base is secured to the under side of the bottom of the box and, since the lid of the box is similarly constructed, it is apparent that the means uniting the side wall with the top of the box is diflerent from the means uniting the cover portion-of the box With the top. Further, according to this invention and in the broadest sense, the side wall of the box has permanent connection with the bottom of the box before the base is applied. As herein specifically shown the permanent connection between the side wall and the bottom of the box is obtained by forming theside wall integral with the box. So, too, in the lid of the box permanent connection between the side wall and the top is obtained before the cover portion of the lid is applied. by forming the side wall of the lid in the same piece, that is to say, integral with the top of the lid. The invention in this respect, however, may be varied Without departure from the principle thereof.

A permanent connection between the side wall and the bottom of the 'box having been provided and the ends of the side wall being in abutting contact or close to each other, a permanent attachment between the ends of the side wall is provided to hold the side wall permanently in proper adjustment. As shown, a continuous strip of paper 6 is folded to enclose the side wall of the box. This strip 6 crosses the abutting ends of thetabs 5 and has its ends out of alinement with any of the ends of the tabs 5. This strip of paper 6 completes the wall and is adhesively secured to the inner and outer sides. Accordingly, after the strip of paper 6 is applied and is attached to the inner and outer sides of the wall, it is impossible for the wall sections comprising the tabs 5 to separate or to fold outwardly.

A base 7 is then attached to the outside surface of the box bottom 1 and it will be noted that the marginal portion of the base 7 projects beyond the side wall of the box and thereby guards and shields the connection between the side wall and the bottom of the box. Further, the base 7 is held in connection with the box by means other than the means holding the side wall in connection with the bottom of the box. 7

In the specific type of box described the rear portion consists of a straight wall 8 extending in a straight line from a point on the upper outer marginal portion of one lobe of the curved base 7 past the rear intersection 9 of the base lobes at the center of the base to a point on the upper marginal portion of the other lobe. Relatively short side wall sections 10 extend from the ends of the portion 8 outwardly and forwardly, and longer side wall sections 11 extend forwardly and inwardly from the ends of the sections 10 and are joined at 12 in a forwardly directed box point adjacent to but spaced from the lower intersection of the side edges of the lobes of the base 7. Thus, the marginal portion of the base 7 projects beyondthe side wall of the boxthrou'ghout the circumference of the box and functions not only as an ornamental feature, but also has utility in shielding and guarding the connection 'of the side wall of the box with the bottom. Moreover, since i the base is united with the bottom, it is possible to use different fastening means, thus greatly reducing the cost and time required to produce thisbox in quantities.

Incompleting the box of my present invention the operation is greatly expedited and facilitated and the cost is largely reduced because of the novel features of construction and relationship of parts. Inthe specific embodiment of the invention shown the intersection 9 of the edges of the lobes constitutes a defined point that is to be located midway of the sides of the box; and the sharp point 13 of the base is diametrically opposite from the defined point 9 and is to be located directly and in a straight line in front of the box point 12. Thus by locating the base 7 in a position in which the defined point 9 is midway between the sidesof the box, that is to say midway between the ends of the wall 8, and in which the sharp point 13 is directly. in front of and in line with the box point 12 a relationship and adjustment is obtained in which the marginal edges of the base 7 at similar opposite points are equidistant from the side wall of the box. The attachment of the base 7 to the box in this way may be obtainedmuch easier and faster than is'possible in constructions whereby the base is secured to the box by the same fastening means that unites the side wall to the bottom of the box. In large quantities this saving is great so that it is apparent that I have produced a box of novel constructioncomprising novel features arranged in a new relationship whereby many advantages and savings are obtained.

The base 7 being of cardboard is, of course, cut to the proper shape and, since said base is-attached to the box by means other than the means holding the wall 5. in connection with the bottom of the box, the edges of the base 7 remain uncovered. By using cardboard of appropriatequality no covering is needed for the edge. The necessity of covering the edge to obtain proper ornamental effect and finish is eliminated because of the omission of the usual attaching strip for securing the base to the side wall of the box. That is to say, the line of connection around the bottom of the box and between the base and the bottom and side wall of the box is uncovered. Heretofore it has been usual .tounite these parts by attaching strip running along the joint or corner, and to obtain proper finish the edge of the base has been cbvcred or enclosed. By my improved box c'on structed as described, this item. ofexpense is.

side wall sections 10* corresponding to the short side wall sections 10; longer side wall sections 11 corresponding to the side 'wall sections 11-; a point 12 corresponding to the,

box point 12; anda sharp point-13- corresponding to the sharp point 13, all of which features have been described above.

"The construction and arrangement of the parts may be varied within equivalent limits 1 perpendicularly from said bottom andforming an enclosure and having a point toward oneside of the box and having 1ts ends close to each other, a strip adhesively united to the outer side of said side wall and crossing said ends and holdingsaid ends from separating,
